What is the error of segmentation?
segmentation failure is a computer error that occurs when the program attempts to access the memory area invalid in an invalid manner. These errors can be read errors where data is made to read data that has not been properly initialized, or write errors where the program attempts to write data for incorrect location in memory. In computer language, the term is often shortened to the segfault. Since segfaults may occur when reading and writing data, they may occur in different contexts with different specific names, including bus errors, buffer overflow, page disorders and storage violations.
Although segmentation failure can be created in some computer languages more easily, they are not part of computer languages. Theoretically, any computer language can cause data writing error that causes segfault. Computer languages that allow a programmer to explicitly process memory such as C ++, allow the user to introduce unintentional relativel segfaults easily withPoor programming. Languages that do not allow explicit memory management, such as Java, can handle most of the memory problems without disturbing the programmer, and therefore minimize segmentation disorders by providing the programmer to use the areas out of the assigned memory.
ways the programmer can create a segmentation error differ depending on the way the data is used. There are certain constructions with which this error is easier to create. One of the common culprits of Segfault is the error overflowing of the field in which the specific data is contained in the slots in a specific memory location, but the programmer is trying to access the slot that does not exist. It is often difficult to track Segfaults created by these situations. Some computer languages have border control, which assumes this type of error and will not let the user try to access the Invalid Slot.
lessThe common way to generate segfault occurs when two computer languages transmit data between themselves using a proxy. In this context, it is difficult to diagnose segmentation failure, because it is not always clear from what language or layer of programming code the error comes from. Although one layer has implicit control boundaries and does not allow segfault in 99.9% contexts, it can be a very time -consuming and tiring work to determine where the error came from.
The best way to avoid segmentation disorders is to be very careful with memory management. Most good programming procedures recommend that users explicitly liberate every byte of memory that is manually assigned in the program. This is often difficult, but it properly increases the chances of a programmer to create a robust flawless program.
